Supreme Sound Opamp V5i Datasheet The Supreme Sound Opamp (SS Opamp) is a specialized, single-purpose opamp for high quality analogue audio amplification. Unlike the general-purpose IC opamp designs, which focus on high open loop gain, Burson aimed to achieve low open-loop distortion, low noise, low drift and low offset. The Supreme Sound Opamp also exhibited a wider bandwidth and wide power supply range. These qualities are essential in high quality analog audio amplification. The input stage features a pair of field-effect transistors. The main amplification section employed a current mirror configuration instead of the conventional voltage amplification. By keeping the current limiting resistor to a minimum value we minimized RC parameter of the circuitry, and hence achieved a wider frequency response. The SS Opamp suitable for a wide range of audio applications.
